SPECIFIUATIQN formingpart of Letters Patent No. 679,418, dated July 30, 1901. Application filed November 15, 1900. Serial No. 36,588. (No model.)

To to whom it may concern.-

Be it known that I, ROY DODSON, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in flame-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hame-fasteners.

The object of the invention is to provide a fastener which is simple of construction, cheap of manufacture, easily applied, and in which the members are adapted to be easily and quickly connected and disconnected.

To this end the invention consists in a hame-fastener embodying certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a perspective view showing the application of myinvention. Fig. 2 is a bottom plan view thereof. Fig. 3 is a longitudinal view. Fig. 4 is a detail view of one of the links of the chain.

Referring now more particularly to the drawings, the numeral 1 designates a pair of hames of ordinary construction provided at their lower ends with rings or eyes 2, and 3 and 4 designate the members of the improved fastener.

The fixed member 3 of the fastener comprises a curved plate formed or provided at one end with a hook or analogous connection 3" for permanent engagement with the eye 2 of one of the hames. At its opposite or free end said plate is provided with side flanges 5, depending from the opposite side edges thereof. These flanges have forwardly-projecting port-ions 6, connected by a fixed pin or pintle 7, on which is loosely mounted a friction-roller 8. In rear of this roller a catch 9 is mounted and consists of a plate formed upon its opposite side edges with trunnions 10, which turn in openings 11 in the flanges and pivotally connect the catch thereto. At its rear end the plate is curved downwardly to form a thumb-piece 12 and at its forward end is provided with a locking-tongue 13. This tongue is adapted by the swinging of the catch to move into and out of engagement with the lower rear portion of the roller. The other or movable member 4 of the fastener consists of a chain provided at one end with a hook 14 for engagement with the eye 2 of the other hame and at its opposite end with a ring or handpiece 15 for convenience in manipulating it. The hook 1a is adapted to detachably engage the eye of the cooperating hame, and the chain extends through the space or opening formed by the forward extensions of the flanges 5 and between the roller and catch. The links 16 of the chain are of the open rectangular type and of peculiar construction, each being curved segmentally in a direction longitudinally of its length and provided at one side 'with an eye 1'7, connecting it to the other link and serving as a frictional retracting surface to throw the tongue of the catch out of engagement with the link. By curving the links in the manner stated said links are adapted to conform to the contour of the periphery of the adjacent side of the roller and to exert an effective pressure to hold the tongue of the catch in locking engagement, whereby a secure locking action is effected.

In practice the fastener forms a permanent attachment, the hook 3 of the plate 3 being permanently connected with the eye of one hame, and when it is desired to connect the ends of the hames the hook 14 of the chain is engaged with the eye of the other hame and the chain then pulled downward to draw the said hame ends toward each other to the required extent. As the ring is pulled upon to tighten the chain an automatic locking action ensues, the tongue of the latch alternately engaging the links and being retracted by the link-eyes, thus preventing casual slipping and disengagement of the chain. To disconnect the hames, it is simply necessary to simultaneously press upon the thumbpiece of the latch and to pull the lower end of the chain away therefrom, whereupon the chain will readily slacken, so that the hook 14 can be conveniently released.

The construction and mode of operation of the invention will be readily understood from the foregoing description, and it will be seen i that a simple, cheap, durable, and effective form of hame-fastener is provided. While the preferred embodiment of the invention is as herein disclosed, it will of course be understood that changes in the form, proportion, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In a hame-fastener, the combination of a plate provided at its outer end with means for connection to one hame and at its inner end with side flanges having forwardly-extending portions, a roller mounted in said forwardly-extending portions of the flanges, a catch pivoted to said flanges and having at and operated substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ROY DODSON.
